What are my options to stay in US

Generally speaking, a nonimmigrant is supposed to maintain legal status at all times in the U. S. That means that you would have to cover the gap if your current employer dismisses you from mid-August until October 1 if you wished to stay here legally. You could conceivably request a B-2 change of status to cover the time until then. I also note that if the H-1B petition was already approved with a change of status on October 1, U.S.C.I.S. would not be looking for any other papers for you from August-October and the subject would probably only ever come up if you went overseas to obtain the visa in the passport.
